PAPER-FILE.

SPECIFICATION forming part of Letters Patent No. 398,316, dated February 19, 1889. Application filed February 10, 1887. Renewed October 27, 1888. Serial No. 289,342. (No model.)

To aZZ 2071 0112 it may concern.-

Be it known that I, MELvrLLn E. DAYTON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Files; and I do hereby declare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to paper-holding de vices or files in which are employed two par allel arches to hold the papers, said arches being composed severally of a fixed and a movable wire, whereby the arches are adaptedto be opened and closed to admit or discharge the papers.

The invention consists in the several matters hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of the operative parts of a file containing my improvement. Fig. 2 is a vertical section taken midway between the parallel arches. Fig. 3 is a top or plan view of the working parts of the file. Fig. 4 shows an alternative form of the adjacent ends of the wire which form each of the arches. 1

A represents a tablet or base of any character, commonly a thin board a little larger than the sheets to be filed.

B B are parallel and equal arches adapted to be opened and closed to permit papers to be applied to or removed from the file or transferred from one part of the arches to the other. The arches B are severally composed of the fixed vertical receiving'wires B and the curved or arched transfer-wires 13*, the free ends of the transfer-wires being in alignment with the fixed wires when the file is closed, and either in actual contact therewith or proximate thereto, so that papers strung on the wires B may be transferred to the wires 13 or vice versa, in the familiar mode of use characteristic of this well-known class of files.

The invention here presented relates to the manner of moving the transfer-wires to permit the application of papers or a considerable number of papers to the receiving-wires or the removal of the entire or a large part of the contents at one time, as when such content-s are to be transferred to permanent filing-cases for preservation.

In former structures employing parallel twopart arches the transfer-wires or the receiving-wires have been hinged at thelower ends to'the base or in vertical. slots, or have been laterally movable along the base from or toward the other or stationary wires.

In one instance set forth in the patent to Shannon, No. 217,907, dated July 29,1879, the arched transfer-wires are rotatable on their vertical axes in the base, and in another the arched wires are not only so rotatable, (separately,) but are bodily removable from the file by lifting them separately from sockets on the base in which their lower ends rest. In the construction last referred to the transfer-wires are separately held in the sockets of the base by set-screws, one holding each wire, and to bring and hold the arched wires in alignment at their free ends with the receiving-wires said arched wires are flattened on one side where the set-screws bear thereon.

The present invention contemplates a separation of the wires forming the severalarches by a simultaneous vertical movement of both the arched transfer-wires I3 and it does not involve the rotation or the vibration of said transfer-Wires. The transfer-wires B rest at their lower ends in sockets C in or upon the base, but are rigidly connected to each other above the sockets by a crossbar, B

D is a spring-catch, which engages the crossbar B to hold the transfer-wires down in proper relation to the receiving-wires to pen mit the transfer of papers from one to the other. It is also constructed, as here shown and as preferably employed, with a capacity for holding the transfer-wires at a little elevation above their normal or lowermost posi tion to permit the free introduction of papers singly or in small numbers at a time, and this, it is suggested, will be the better posi tion of the receiving-wires for convenience, except when it is desired to transfer the papers to the arched Wires, in which case the latter will be lowered into j uxtaposition with the receiving-wires.

E represents a spring or springs placed beneath the cross-bard), which, in this or some other form, is desirably present for the purpose of lifting the connected transfer-wires.

Then upon pressing the thumb against the upper end of the spring-catch D the crossbar B automatically rises and engages the higher notch of saidcateh, so that the shifting of the position of the transfer-wires to this more elevated position is an operation conveniently and quickly performed. The spring is, however, not indispensable, as the catch may itself sustain the transfer-wires.

I prefer to provide the catch D with an arm I 5 projecting toward the plane of the receivingwires in order that the catch may be more conveniently detached from the cross-bar when a bodyol' papers occupies the transferwires and covers the catch proper.

The cross-bar may bclocated at any des red elevation on the transfer-wires and the sockto hold the connected transfer-wires in two position at all points in their vertical movement, substantially as described.

2. In a file having two severally-separable parallel wire arches, the combination, with a base and two receiving-wires, of two arched transfer-wires rigidly joined by a cross-piece above their lower ends, and vertical guides on the base fitted to the lower ends of the trans-. fer-wires below the cross-piece, substantially as described.

In a file having two severally-separable parallel wire arches, the combination, with a base and two receiving-wires, of two rigidlyconnected arched transfer wires, vertical guides for said connected transfer-wires,whicl1 retain the latter in an upright position, and a catch having two notches or corresponding points of engagement, and which is adapted positions, si'il'istantially as described.

ets may be lengthened, so that the transfer- 35* their vertical position at all points of their elevation; but any other form of interfitting projections and guides, of which many are familiar, will do as well.

T claim as my invention 1. In. a file having two several]y-separable parallel wire arches, the combination, with a base and two receiving-wires, of two arched transfer-wires rigidly joined by a cross-piece, guides for the lower ends of the transfer-wires, 45 which permit vertical movement of said trans fer-wires, and which retain them in a vertical transfcnr-wires down in opposition to the ac- 4. The combination, with a base and two receiving-wires of a double-arch file, of two rigidly-joined arched transfer-wires, means for guiding said connected transfer-wires in a vertical direction, a spring or springs arranged to exert a lifting force on the transfer-wires, and a catch arranged to hold the tion of the spring, substantially as described.

5. The combination, with a base and two receiving-wires of a double'arch file, of two rigidly connected arched transfer wires, means for guiding the connected transferwires in a vertical direction, a spring arranged to bear upwardly upon the connected transfer-wires, and a double-notched spring-catch constructed to retain the transfer-wires in two positions in opposition to the action of the spring, substantially as described.

In testimony that I claim the foregoing as my invention I allix mysignature in presence of two witnesses.
